Change from E class to used Phaeton

A hello to all Phaeton ler I have been following your posts with great interest for some time. I once had the honor of moving the V10 my almost father-in-law. A smooth affair. What I like about Phaeton is the unobtrusive appearance and the lavish space offer as well as the impeccable processing continues to be the very favorable used car prices. For me would be a used Phaeton (BJ 2008/2009) an alternative to a current e-class (also used) (BJ 201/2011) Important criteria for me is the topic of rust. Is there at Phaeton also the topic rust? The MB W210 is a disaster in this regard. my wish Phaeton would be V6 tdi 3.0 ;ACC; Extended wooden package; Beige leather; Seats front 18 path adjustment. Climate control unit behind; The 4 seaters are more valuable however, the large tunnel seems to be a bit more difficult for me. Probably rather the seat bench. I would like the long version. So far I have mostly had to let my W210 fix everything myself with the expensive purchase of staff as well as well as I have often have written suggestions for me here.
